A teenager has been arrested after killing nine people and wounding four others in a knife attack in northeast China, state media reported Thursday.

The 17-year-old, who was identified only by his surname Li, barged into the home of his girlfriend armed with a knife following an argument and killed two relatives of the girl, the Legal Daily said. As he left his girlfriend’s home in Liaoning province’s Xinbin county, he stabbed six more people to death and wounded five, it said. One of the injured died Thursday in hospital, the paper said.

Li was arrested near the scene of the attack, late on Wednesday night, and was taken into custody, the official Xinhua news agency reported. Police had nabbed him as he was preparing to jump from a building in an apparent suicide attempt, it added. No other details were immediately available. Calls made to local authorities and police in Xinbin county went unanswered.

Violent crime has been on the rise in China in recent decades as the nation’s economy has boomed and the gap between rich and poor has expanded at an alarming rate. Experts say the increase in assaults shows that China is paying the price for focusing on more than 30 years of economic growth while ignoring problems linked to rapid social change.

What do you think drove this Chinese teenager to attack those people with a knife? Do you agree that economic stress in China has greatly contributed to increasing mental health concerns among its citizens?

The recent shooting rampage at a movie theatre in Aurora, Colorado, reminds everyone of the familiarity of this kind of tragedy in America. It has happened so many times. Each time, different set of numbers are reported — 12 dead, four guns, 6,000 rounds of ammunition bought online — but other numbers ought to be brought to the public’s attention.

In America alone, there are more than a dozen guns being sold legally every minute of every day. In the U.S., there exist nearly 300 million privately-owned firearms — that’s enough to arm the whole population. Four out of 10 American homes have a gun. However, only a fraction of these owners have the bulk of the weapons, and each year, a gun collector’s number of items increases.

Because of the enormous amount of supply, prices of guns have gone down. James Holmes, the suspected gunman of the Batman movie massacre, has an arsenal that is estimated to cost $3,000. Bullets are prices at around 50 cents each. So, with roughly the price of a tank gas, he could already have filled his AR-15 with 100 rounds of ammo.

According to the National Rifle Association, more guns means less crime. They say that since the early 90’s, when a lot of states went slack with their weapons laws, the rate of violent crime has decreased by 70 percent. In spite of the shooting rampages in schools, military bases, and other public places, the national murder rate has remained low for 47 years already.

On the other hand, the Brady Center to Prevent Gun Violence, a non-profit organization, reports that among all the races, Americans are the one that have the highest level of killing each other using guns.

A study cited in the Journal of Trauma and Acute Care Surgery found that U.S. has a gun murder rate of 19.5 percent — that’s nearly 20 times above the gun murder rate of the next 22 richest countries combined! In addition to that, looking at the world’s 23 richest nations, 80 percent of all gun deaths are American deaths and 87 percent of all kids who died by gunshots are actually American kids.

Despite these publicized numbers, public attitudes remain the same, even after another fresh round of a shooting rampage. Forty-nine percent of the people say that it is more important to guard gun rights and 45 percent agree to a stricter gun control policy. But no one can deny the detrimental effects of our itching gun collectors’ hands. And the biggest effect is human death.

Children’s Defense Fund says within the 44 years since Bobby Kennedy and Martin Luther King were assassinated, guns and bullets have put an end to the lives of over a million people — and that number already includes the 12 innocent people who died in Aurora, Colorado, who came together for a midnight movie just to watch and cheer for their favorite superhero. Sad, isn’t it?

With the recent shooting rampage in mind, are you in favor of a tighter gun control? Or do you prefer to protect the rights of gun owners?
